Another vote for Paris - I quite like it on a girl as well actually, but I love it for a boy and I'd use it, definitely.

I also think Brooke on a boy would be lovely, although I prefer the spelling Brook. I like Addison and in the UK it's still pretty rare as a name but you do hear of the odd girl Addison so unfortunately I think the trend is crossing over here

I used to be way more uptight about this though. I think names that have historically been boy should stay there, and surnames with particularly masculine meanings or connotations should stay on boys, as well as surnames ending in -son. I don't mind nature names or place names on either gender, and surnames like Harlow etc. are fair game for either as well.
